In about half an hour, I plan to set the tag for the 0.28.beta1 release. From that on, we will be in the beta period.
This release is done with one outstanding P2 issue (issue 5562). Bob has promised to take care of that in the next couple of days so I am confident that there will be no problems.
If there are any last minute commits for the alpha period, please be quick to contact me. I will run the tests now and then start the release.
